WATCHES AND WARNINGS ——————– There are no coastal watches or warnings in effect.

DISCUSSION AND OUTLOOK ———————- At 1100 PM AST (0300 UTC), the center of Tropical Storm Isaac was located near latitude 14.9 North, longitude 64.4 West. Isaac is moving toward the west near 16 mph (26 km/h), and this general motion with a decrease in forward speed is expected for the next few days. On the forecast track, Isaac will move over the eastern and central Caribbean Sea during the next few days.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Isaac is forecast to gradually weaken over the next few days, and could degenerate into a tropical wave at any time.

Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center.

The estimated minimum central pressure is 1006 mb (29.71 inches).

HAZARDS AFFECTING LAND ———————- RAINFALL: Isaac is expected to produce additional rainfall of 2 to 3 inches with isolated amounts up to 5 inches across the northern Windward Islands into the Leeward islands, and southeastern Puerto Rico. Totals of 1 to 2 inches with maximum amounts of 3 inches are possible across the remainder of Puerto Rico, the Virgin Islands, Dominican Republic and Haiti. This rainfall may cause life-threatening flash flooding.

SURF: Swells generated by Isaac are still affecting portions of the Lesser Antilles. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
